Solution Overview
Problem
Autonomous vehicle sensors often require professional calibration due to the need for precise placement of calibration objects, which is beyond the capabilities of ordinary consumers, leading to the necessity of bringing vehicles to dealerships for service.
Innovation Solution
Systems and methods for calibrating sensors in autonomous vehicles using a calibration guide that indicates the correct location and positioning for a calibration object, including a laser guide, extendible arm, or autonomous robot to facilitate auto-calibration, allowing users to perform calibration procedures without professional assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a calibration object is placed in a predefined position with substantial precision for sensor calibration, then measurement precision is improved, but device complexity and ease of operation deteriorate because it requires professional expertise and dealership visits
Solution Approach 1:
The system enables consumers to perform sensor calibration themselves without professional assistance. The calibration guide provides automated guidance including visual indicators and positioning assistance, allowing the end user to complete the calibration procedure independently at home rather than requiring dealership service.
Solution Approach 2:
The calibration guide acts as an intermediary between the calibration object and the sensor system. It provides positioning indicators, alignment guides, and automated detection to bridge the gap between simple user placement and the precise calibration requirements, eliminating the need for professional expertise.
2Ease of operation
If a calibration guide with positioning indicators is provided, then ease of operation is improved, but device complexity increases due to additional components
Solution Approach 1:
The calibration guide is divided into separate functional components: positioning indicators, alignment guides, and detection systems. Each component performs a specific function and can be independently simplified. The guide can be implemented as separate modules that can be added or removed without affecting the entire system.
Solution Approach 2:
The calibration guide is designed to work with multiple sensor types and calibration objects using a universal set of positioning indicators and alignment references. The same guide structure can accommodate different calibration patterns and sensor configurations, reducing the need for multiple specialized components.

AI summary
Systems and methods for calibrating sensors for an autonomous vehicle are disclosed. A calibration guide disposed on the vehicle can indicate to a user the correct location for a calibration object to be placed for a calibration procedure. In one implementation, a laser guide can project an image indicating the correct location and orientation for the calibration object. In another implementation, an extendible arm disposed on the vehicle can suspend the calibration object at the correct location and orientation. In another implementation, an autonomous robot carrying the calibration object can autonomously bring the calibration object to the correct location. The calibration guide can be unobtrusively stored within the vehicle when not in use.
